Replacing Unity with XFCE in Ubuntu

Here is what I do as soon as I install a new Ubuntu instance: I remove unity desktop and replace it with XFCE. And if you want to do the same it's pretty straightforward. ;)

Perform all of these as root in a terminal window, or prepend with sudo. (Look elsewhere for GUI steps :) )

1. Update your repos:

   apt-get update

2. Uninstall Unity and ubuntu-desktop:

   apt-get purge ubuntu-desktop unity-*

3. Install XFCE Desktop environment:

   apt-get install xubuntu-desktop

4. Restart lightdm:

   /etc/init.d/lightdm restart

Voilà! You're using XFCE desktop! ;)
